Lockheed During WWII (unbelievable 1940s pictures). This is pretty neat--special effects during the 1940's: I have never seen these pictures or knew that we had gone this far to protect us. During World War II the Army Corps of Engineers needed to hide the Lockheed Burbank [See Note 1] Aircraft Plant to protect it from Japanese air attack. They covered it with camouflage netting to make it look like a rural subdivision from the air. (Besides everything else, check out the cars.)

Note 1:
The Lockheed Marietta plant at this time was owned and operated by Bell Aircraft. For years, even after it was re-opened by Lockheed, we referred to it as 'Bell Bomber'. The bombers being built were Boeing designed aircraft, notably, the B29. It is doubtful that such camouflage was used in Marietta because of its location away from likely access from the sea.
